All,
Say I have an array of nucleotide sequences of of length N. I want to calculate the count matrix (weight matrix). That is for each position 1..N, I want to know how many As, Cs ,Ts and Gs there are. Is the code to do this already written in bioperl to build this matrix if I pass it those strings?
Please excuse my lack of knowledge as I am a new comer to bioinformatics.
Thank you.
Sincerely,
Sam Al-Droubi, M.S.
